Many issues with my B4000 and no diagrams of the engine anywhere to be found...I'll start with the main problem. A hose somehow popped out and I can't find the hose or where it goes to. I see where it came from but have no clue as to what it functioned as. My truck can run but the engine shakes and convulses and tries to stall out. Any info on where to find a diagram of the engine or the hoses please let me know. We are going crazy trying to find it. I think it goes somewhere to the EVR but just can't see where...

 

the year would have helped to narrow it down
there should be a label on the underside of the hood with a pic of the vacuum hoses and where they go
i'm sure the b4000 is a ford 4.0L
so here's the ford link
